The center agreed a two-year contract with the team earlier this week, having made his first start at the position for the team last Thursday.
The 30-year-old, who previously played at guard, told the team's website: "It's been a blessing ever since I've come to this organisation.
"I think the path that I've taken has been a tough one and I'm just happy to be here. I'm very happy that the organisation wants me to be a part of it, as well.
"It was never specifically told to me in that way, that I was the starter. But I approached it like I was. Because, again, every year is a new year all over. You're in there competing, there's the competition from everywhere. I don't think there's any other way that you could approach it."
Ramirez joined the Broncos in 2011, having spent the first four seasons of his career with the Detroit Lions.
